My invention relates garbage and refuse incmerators of the type adapted especially foruse 1n apartment buildings, residences, hospitals, and the like; and it has for one of its objects to provide a simple and inexpensive incinerator wherein garbage or refusecan beconsumed conveniently, economically, and in a clean and sanitarymans and which, by means of a smoke pipe or flue, is' connected to a chimney of the building in which the incinerator is situated..

Another object of my invention is to provide a gas-burning dowiifdiaft incinerator, and particularl one in which the air mixes directl with t e'gas above the garbage or refuse ing consumed. i a

A further object of my invention is to provide an incinerator in Whichthe -gas burner is located in a plane above the charging or feedopeiiing, and wherein the ma]or portion, at least, df the garbage or refuse to be consumed occupies the space between said opening and the grate.

' A further object of my invention is the pro vision of an incinerator wherein the gas burner attacks the garbage or refuse from the top, and the flame of the burner burns from the top downwardly so that it attacks, at all times, the portion of the garbage orrefuse having leastmoisture, and by reason of the draft being downwardly through the garbage or refuse, gradually'dries the garbage or refuse from the top downwardly, with the re- .sult that practically all of the garbage or refuse will be consumed and only -a coirparative-v ly small quantity of ash orwaste result from the operation. of incinerating the garbage or refuse. n A

A still further object of my' invention is to provide an incinerator havinga gas burner so disposed therein that the direction of the flame and draft is downwardly through the garbage'orrefuse and wherein the draft pipe or Hue has its inlet-opening in a plane below the lowest portion o the garbage or refuse receptacle or container.' y

A still further object of my inventionis to provide an incinerating chamber having imperforate Wallsand a grate-like or open-work' receptacle or container having a perforated bottom and atleast a rear imperforate wall of the incinerating chamber to form an auxiliary flue, and a draft ipe or flue having an inlet Yconnected vwith tie lower end `oi said auxiliary flue,

With the above and other objects in view to to improvements inappear hereinafter, my invention consists in the novel features-of construction and in the arrangement and combination of parts to be hereinafter described and more particularly pointed out inthe subjoined claims.

In the drawings Fig. 1 is a central vertical se'ction through an incinerator 'constructed in accordance with my invention. I

Fig. 2 is a horizontal section taken on line 2 2, Fig. 1.

Fig. 3 is a horizontal section taken on line 3- -'3, Fig. 1..v f

The reference numeral 4 designates the casing of the incinerator, which. comprises a top wall 5, a bottom wall 6, al front wall 7, opposite side walls 8,and a rear wall` 9, the latter being curved and merging into the side walls 8, as at 10. The front, side, and rear walls' constitute a surrounding wall and each 'comprises an outer wall portion 11 lined with asbestos 12 in sheathing or other suitable form for insulation purposes, and an inner wall portion 13 spaced from said outer wall passage 14, said air space or passage extending from the bottom wall 6 to the topwall 5.

Lwhich is also closed by a'door 20.

Arranged within the incinerating chamber 16 is a basket-like garbage or refuse receptacle or container 21 formedof open -work' or gratelike walls. prises a bottom wall or grate 22, a front wall 23, side walls 24and a rear wall 25, the

This receptacle or container comportion t'oform an intervening air space or front wall being inclined downwardly and `rearwardly from its upper end, as 'clearly shown in Fig. 1, while the rear wall has its lower portion inclined downwardly. and forwardly approximately from a point midway between the upper and lower ends of said receptacle orcontainer to said grate 22; thus gradually'reducingthe-lengtli of the receptacle downwardly. While this formation is desirable, owing to the fact that the front wall` and the lower portion of the yrear wall are thus spaced, gradually increasing distances from the front wall 7 of the casing and the back plate 15,'respectively, it is to be .understood that this garbage or refuse recepcinerator, to provide shaking, rocking or other movable bars; or, if desired, an integral grate movable or rockable in any 'desired manner.

It is to be noted that the rear wall 25-of the garbage or refuse receptacle or container is extended upwardly a considerable distance abovethe upper edge of the side walls of said receptacle or container, as shown at 26. The rear wall of the garbage or refuse receptacle or container is spaced from the rear wall or back plate 15 of the incinerating chamber, and this space serves as an auxiliar flue 27, which extends from the upper end7 of said rear wall downwardly into the ash pit 28 leneath the receptacle or container 21.

rThe receptacle or container 21 may be supported in any practicable manner, but in the lconstruction illustrated, the front wall 23 thereof has a forwardly extending flange 29, which rests upon asupporting rib 30 formed on the front wall Z of the incinerator casing,

while brackets or supports 31 fastened to the rear wall or back plate 15 of the incinerating chamber are secured to the rear wall of said receptacle or container and support the saine from the rear.

The side walls 24 of the receptacle or container 21. are spaced from the side walls 8 of the incinerator casing' so .that the open-work walls of said receptacle or container are spaced at all points from the surrounding walls'of the ineinerating chamber.

The reai wall or back -plate 15 of the in' cinerating chamber has alaterally elongated opening formed therein nearl its lower end, and fittedinto this opening is the correspondingly elongated end of a smoke or draft box 32, the inlet opening ofwhich is therefore of considerable area. This draft box is situated -in the flue chamber 33 between' the rear wall or V4back plate 15 of the incinerating chamber and the curved rear wall 9 of the incinerator casing. This smoke or draftbox is provided at the top with an outlet opening '34, and connected to'this opening is a smoke- A0r draft pipe 35 which extends upwardly through the flue chamber 33 and out through the top 5 of the incinerator casing. To the upper end of' this smoke or draft pipe 35 is adapted to be secured a suitable pipe or f lue leading to a 'chimney of thebiiilding in which the ineinerator is situated, so that connection 4 is had directly withthe incinerating chamber 16 to establish a means of escape for the unconsurned gases or smoke.

36 designatesya gas burner, which may' be chamber 16- a suitable distance above the l garbage -or refuse vplaced within the receptacle or container 21'. This gas burner ex tends out through the vfront wall 7 of the incinerator casing and is adapted to have connection with any suitable source of gas supply and provided with suitable means of con'- trol, as will be understood by those skilled in the art.

The gas burner 36 is directed downwardly so that the flame issuing therefrom Vwill be directed against the top of the garbage oi' refuse contained in the receptacle or container 21.

It is the generalpractice in garbage or refuse incincrators of this type. to fillthe garbage or refuse. receptacle or container with the garbage or refuse andallow `the saineto dry if moisture laden, before the incineration takes place Consequently, the upper portion and imperfect combustion, unless the garbageor refuse accumulated is allowed to remain in the receptacle or container for an iinpracticable length of` time, in r,order to assure complet-e drying of the saine from top to bottom. In this improved incinerator, when the upper portion of the garbage or refuse.

garbage or refuse is freed of moisture; at least to a 'degree found desirable before commencing ineiner! vation thereof, the burner 36 is ignited; The

flame directed against the top of the garbage or refuse will attack and gradually consume the saine, and as thev walls of the refuse receptacle are all provided with openings and the inlet to the smoke or draft box l32 is in a plane beneath said receptacle, it will be clear that the direction of the draft and the effective action of the flame will be 'in a downward course, thus drying out the lower upper. Before the upper portion is fully consumed, the lower portion will be sind ciently dry to en'ablethe flame to consume the same. All the garbage will therefore b e consumed in a shorter period of time than heretofore possible, or will atleast be reduced eliminates smoke and odors and assures clean surroundings.

wardly extended portion of saidv rear wall l lll .portion of the garbage while consuming theto ashes. This .results in a saving of gas,

and thence downwardly, with the result that l the garbage within the receptacle 0r container will also be attacked from the rear, and as the draft in the auxiliary flue 27.1nrear of said rear wall is downwardly, the smoke I tity of air be provi and gases will pass downwardly through said flue, also from the sides of the receptacle or container, and. escape through the inlet of the smoke or draft box 32, from which it will pass upwardly through the smoke or draft pipe and be drawn into the chimney. It is highly essential that the proper quaned to the incinerating chamber, especially to the flame of the gas burner, and for this purpose the bottom wall 6 of the incinerator` casing is provided with numerous air openings 37, said openings being aligned with the air space or passage 1 between the outer and inner wall portions of the casing. The air entering these openings travels upwardly through said space or passage and enters air openings 38 formed in the inner wall portion of the casing at opposite sides ofthe incinerating chamber, preferably at their extreme upper ends. he air thus entering the incinerating casing commingles freely with the gas escaping f the burner 36 and furnishes the proper amount of oxygen necessary to provide a hot flame and to furnish the garbage or refuse where attacked by the fia e, with the necessary quantity of air to assure proper combustion.
